Actin is an abundant cytoskeletal protein found in all cells (True, 1990). The protein's 42kD peptide chain assumes two physical forms: globular actin, which may serve as a cytoplasmic storage pool, and fibrous actin, which, in conjunction with myosin, generates muscle contraction (True, 1990). In non-muscle cells, actin appears to be involved in a variety of functions, such as cell motility, exocytosis, and phagocytosis (True, 1990). Distribution of the six known isoforms of actin-four muscle actins (alpha-skeletal, alpha-vascular smooth, alpha-cardiac, and gamma-enteric smooth) and two cytoplasmic actins (alpha and gamma) is tissue specific.
Applications:
Suitable for use in Flow Cytometry, Western Blot, Immunoprecipitation, Immunohistochemistry, and Immunocytochemistry. Other applications not tested.
Recommended Dilution:
Flow Cytometry: 1:20
Western Blot: 1:1000
Immunohistochemistry (paraffin): 1:100-200
Immunocytochemistry: 1:250-500
Immunoprecipitation: 1:20
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
